A glimmer of hope in our worsening obesity crisis
While the nation’s excess weight sits at 189 thousand tonnes, new research observes a positive shift in 2017
New data suggests 2017 was a better year for our nation’s ever-worsening waistlines, as the percentage of overweight or obese Australians saw a subtle decline.
The data from the latest Medibank Better Health Index1 found that over the past year, the number of Australians falling into the healthy weight range has increased by 200,000 people2, as the mean BMI score declined from 27.44 in 2016 to 27.37 in 2017, and the percentage of those who are overweight or obese dipped from 63 per cent to 62 per cent.
Conducted by Roy Morgan Research, the Medibank Better Health Index is Australia’s most up-to-date and comprehensive quarterly health study. Having interviewed more than 1,000 Australians each week since 2007, the Index offers an in-depth look into the state of the nation’s health and how it’s changing.
Young Australians lead the positive shift
According to the data, young people led the past year’s positive trend, with the percentage of overweight and obese Australians dropping from 37 to 35 per cent amongst 18-24 year olds, and 57 to 54 per cent amongst 25-34 year olds. This is compared to 35-49 year olds, which saw a negligible shift, and 50-64 year olds, where the percentage of those who are overweight or obese in fact increased from 71 per cent to 73 per cent.
Australia’s obesity issue remains at crisis levels
Despite this apparent shift in the right direction, the Index confirms Australia’s mean BMI is still firmly in the overweight range, with the percentage of overweight and obese Australians having soared over the past decade, remaining significantly higher than 10 years ago3. What’s more, the latest data found overweight and obese Australians are currently carrying an extra 16.7 kilograms per person on average, with our nation’s excess weight sitting at 189 thousand tonnes.
According to Medibank Chief Medical Officer Dr Linda Swan, Australia’s obesity issue remains at crisis levels and represents one of the greatest public health challenges facing our nation. The issue contributes to a range of health conditions, including type 2 diabetes, cardiovascular disease and certain cancers.
“Although these findings suggest a potential swing in the right direction, it’s important to bear in mind that this data reflects a subtle change over a relatively short period. And while we hope to see this decline become a more pronounced trend, it’s too soon to tell whether it will represent a meaningful change in our national weight over time,” said Dr Swan.
“In the meantime, it’s important all Australians take steps to maintain a healthy lifestyle -- with regular exercise and a balanced diet -- to help keep their weight in check.”
Staying healthy as you age
Dr Swan acknowledged that it can be more challenging to stay active as we age, as juggling family, work and potential health conditions are more likely to impact our ability to regularly exercise.
“However, we also know that the incidence of certain weight-related conditions increases with age, which means it is even more important to keep your weight in check as you grow older,” she said. “The good news is that it’s never too late to implement healthy lifestyle habits, and every little bit helps.
